Hello, A little while back we setup a self-contained server for a client for their website and e-mails. We installed ISPConfig3 on it for managment, and it has been great. We have a multi-server setup for our own virtual client hosting of websites and DNS, and I was wanting to bring this client server into the fold, and am wondering what the best way to do it might be? It has one website and 100+ IMAP mailboxes. I would like it t be seamless as possible for the mail users. I saw that there is a migration tool which would seem to be perfect, but I am not sure if it would have any negative effect on our current multi-server setup. What I am thinking to do is this: Setup a new dedicated server for the client to use and add it to our current multi-server setup Create the necessary settings in the client's "Limits" tab so websites, e-mails, etc. will only get created on their server for them Use the migration tool to migrate everything from their current server to the new one Point the IP of their current server to the new one As I said, though, I am not sure if that would mess anything up with our current setup, or will it import everything over (hopefully) without issue? I guess my question(s) just boil down to: is the migration tool intended to migrate to a new, fresh system without anything else on it, or will it work just fine importing into an existing system with sites and DNS already setup on it? Thanks!
